The value of the attribute is copied from the value buffer For string-valued attributes, the string stored in the value buffer must be NUL-terminated If a string is longer than 32 bytes (including the terminating NUL), it is silently truncated to fit The function fails if attempts are made to set an attribute in a device that is not on-line or attempts are made to update a non-existent or read-only attribute Here is a C code fragment that updates the value of the location attribute of device 686:

The basic shape of thermometer servants is determined by the skeleton class produced by the IDL compiler The thermometer servant must at least provide implementations for the four attributes in the Thermometer interface, so the basic class header looks like this:

Although we could leave this class as shown, we require a few more features for convenient use in our server The basic strategy for this implementation is to have one servant instantiated in memory for each device on the network Each servant keeps its own asset number in a member variable called m_anum The asset number (which is also an ICP network address) serves as the identity of each device As you will see in Section 106, we use implementation inheritance to implement thermostats; the Thermostat_impl servant class inherits from the Thermometer_impl class in order to reuse its implementation To allow the derived Thermostat_impl class to access its own identity (provided by the base class), we make m_anum a protected member, and, because the identity of a device is immutable for its lifetime, the m_anum is a const member The ICP API is not exactly a model of convenience This suggests that we add private helper functions to the Thermometer_impl class to hide the details of accessing device attributes via the ICP API We therefore add the helper functions get_model, get_temp, get_loc, and set_loc to the class Our object model contains the controller as a singleton object As you will see in Section 1053f, it is useful if each servant can access its controller object Rather than make the controller a global variable, we add to the class a public data member called m_ctrl of type Controller_impl *, which points at the controller servant singleton Because the member is static, it is shared by all thermometer and thermostat servants Our class will need a constructor and a destructor For each instantiated device, the server must specify at least the asset number of the device For this implementation, the constructor also accepts a location string This is necessary because for now, our simple server will have a fixed number of devices at predetermined locations (We discuss in 12 how clients can dynamically add and remove devices)

As with all servant classes, we hide the copy constructor and assignment operator for the class because copy and assignment do not usually make sense for servants These points result in a class definition for Thermometer_impl as follows:
